Description

The scarlet-tufted sunbird is a large sunbird. Adult males have long tails, up to about 20 centimetres (7.9 in) in length, and scarlet pectoral tufts up to about 10 millimetres (0.39 in) wide.[3] These tufts can be seen in flight and when the wings are rearranged, but not in perched birds. The head is black and the upper parts are metallic green, appearing almost black from a distance. The rump is bluish and the wings and tail black, the latter having elongated central feathers. The underparts are iridescent green, fading to bluish-violet on the upper belly and black on the lower belly. The female has brownish-grey upper parts, brownish-black wings and a dark brown tail. The underparts are whitish with dark mottling. The pectoral tufts are smaller than those of the male and may be rather more orangey-red. The juvenile is similar to the adult female but lacks the pectoral tufts.[4]

Distribution and habitat

The scarlet-tufted sunbird is found at very high altitudes in the Afroalpine Rwenzori-Virunga montane moorlands and East African montane moorlands, though also found at lower altitudes. Its normal range is on several disjunct areas of montane forest and moorland between 3,000 and 4,500 m (9,843 and 14,764 ft) in altitude, which encompasses a number of zones of vegetation. It is especially associated with giant lobelia, feeding on the nectar and insects on the plants, and using the tall flowerheads as song-posts. At lower altitudes it feeds on Protea and other plants.[4]

Status

The scarlet-tufted sunbird is a common species with a small range, and the population trend is thought to be steady. No particular threats have been identified and the International Union for Conservation of Nature has assessed the bird's conservation status as being of "least concern".[1]

gollark: Which one, the orbital lasers or rules?
gollark: *Or* precommit to using orbital lasers to destroy anyone who dares violate the pact.
gollark: You could... make this agreement on Switchcraft, which would make them bound by the rules (apparently) to follow through?
gollark: REAL men send a specially crafted set of data and stall it until precisely the right time so that the random number generator will pick them.
